terragpu

Python library to process and classify remote sensing imagery by means of GPUs and CPU parallelization for high performance and commodity base environments.

We are currently working on tutorials and documentations. Feel to follow this repository for documentation updates and upcoming tutorials.

DOI Pipeline Status

Objectives

  • Library to process remote sensing imagery using GPU and CPU parallelization.
  • Machine Learning and Deep Learning image classification and regression.
  • Agnostic array and vector-like data structures.
  • User interface environments via Notebooks for easy to use AI/ML projects.
  • Example notebooks for quick AI/ML start with your own data.

Installation

The following library is intended to be used to accelerate the development of data science products for remote sensing satellite imagery. terragpu can be installed by itself, but instructions for installing the full environments are listed under the requirements directory so projects, examples, and notebooks can be run.

Note: PIP installations do not include CUDA libraries for GPU support. Make sure NVIDIA libraries are installed locally in the system if not using conda.

Background

Library to process and classify remote sensing imagery. This is work in progress currently supporting Random Forest classification and merging Convolutional Neural Networks from the deep-rsensing project. Each particular project includes its own README with information.

Raster processing relies in xarray and rasterio for memory mapping operations, using Dask as the backend. PyTorch is implemented for GPU accelaration of Sckitlearn models. GPU acceleration is provided by the NVIDIA RAPIDS environment and we are in the development phase to support AMD GPUs.
